Sounds like it could be your 3 way diverter valve sticking or jammed in mid position, should imagine one of the more experienced Plumbers will be along soon though, I've forgotten so much

If the heating is off but rads are warm, then I reckon either the valve (mid position valve) that diverts the boilers heated water into the heat exchanger in the storage tank is duff, or you plumbed one leg of the new radiator into the hot water pipes.

Probably worth checking your valve if you have one, if its a Honeywell like this http://www.uk-plumbing.com/honeywell-3-port-mid-position-valve-v4073a-1039-22mm-p-1415.html then there is a notch in the casing to manually keep the valve open, as seen. The plumber may have left it on manual and it could be a case of just flicking a lever off its notch.
